16 BULLETIN 250, U. S. DEPARTMENT OF AGRICULTURE. 



In the trays, both at Worcester and Melrose Highlands, larvae started in the 

 first stage died on or before reaching the third stage. 



American Hoenbeam (Carpinus caroliniana Walt.). 



All larval stages feed upon this foliage, and defoliation results in badly 

 infested territory. 



This species was tried in both laboratories, and first-stage larvae died on or 

 before reaching the third stage. 



Hop Hornbeam (Ostrya virginiana [Mill.] Willd. ). 



In the tray experiments at Melrose Highlands and Worcester first-stage larvae 

 failed to develop beyond the third stage on this foliage. 

 Larva? feed on this foliage in all stages in the field. 



Highbush Huckleberry (Gaylussacia baccata [Wang.] Koch). 



This is an unfavored food plant and will not sustain the larvae until they are 

 full grown. The observers report seeing the larvae in all stages feeding upon 

 this species; in most cases they were probably larvae that had spun down from 

 overhanging trees. 



In the trays a few male moths were obtained from larvae started in the second 

 stage. 



Inkberry (Ilex glabra [L.] A. Gray). 



In southeastern Massachusetts this species is common over large areas. 

 Tray experiments and field observations both show that the larvae can not 

 subsist upon it. 



Smooth Winterberry (Ilex laevigata [Pursh] A. Gray). 



Larvae have been reported on this species in all stages eating small holes or 

 notches in the leaves. These were probably larvae that had been shaken down 

 from overhanging trees or had crawled from near-by species. None seemed to 

 stay for extended feeding. 



In the trays there was very slight feeding and no growth. The caterpillars 

 died rapidly of starvation. 



American White Holly (Ilex opaca Ait.). 



Mr. Schaffner reports finding larvae in the third, fourth, and fifth stages feed- 

 ing slowly on this species. 



Larvae in the trays fed sparingly in the first stage, but died rapidly of starva- 

 tion. In the succeeding stages there was hardly any feeding, and death resulted. 



Feverbush (Ilex verticillata [L.] A. Gray). 



Tray experiments and field observations show that gipsy-moth larva 1 will not 

 subsist on this species. A few small notches in the leaves observed in the field 

 and notches and small holes in the leaves in the trays constituted all the feed- 

 ing. Larvae died rapidly and did not grow at all. 



Larger Blue-flag (Iris versicolor L.). 



Mr. Kennedy found fourth and fifth stage larva?, feeding on this species in 

 Hampton, N. IT. The swamp was situated near a group of gray birches that 

 were badly stripped; the larva? wore being blown off by the wind, and in search- 

 ing for food crawled to these plants and partially defoliated them.
